This pipe boulder opal weighs in at over 13 carats and displays a stunning palette of colors. I've set the stone in fine and argentium sterling silver and add a fringe of colorful gemstones:
tigers eye
pink sapphire
tanzanite
rhodolite garnet
amazonite
The ring focal sits on a double wire band and is currently a size 7 1/4. I can enlarge up to a 7 3/4.
